A process for operating an electric-motor drive is proposed for adjusting a sliding-lifting roof (16) in a motor vehicle by means of a signal processing arrangement (20), with a microprocessor (21) to which is fed an adjusting command (23) of an operating control (22) for a reference position of the sliding-lifting roof (16) as an actual state signal and at least one additional actual state signal of at least one arrangement (26, 32, 34, 52, 54) for detecting the actual position of the drive (10) and/or of the sliding-lifting roof (16), and which microprocessor (21) controls or regulates the drive (10) for moving the sliding-lifting rood (16) to its reference position, wherein the actual state signals are detected cyclically by the microprocessor (21) and a response is read out of a storage depending on the signal combination, wherein the response determines whether or not, and in what manner, the possible adjustments of the operating control (22) lead to a change in the present drive behavior via the signal processing arrangement (20).
